IMPROVEMENT IN COMBINED WRENCH AND PIPE-CUTTER.

' Specification forming part of Letters Patent No. 183,485, datedOctober 24, 1876 application filed June 2, 1876.

To all whom it may concern:

Be it known that I, JOHN BREWER, of the city of Brooklyn, in Kingscounty, and State of New York, have invented an lmprovement in aCombined Pipe -Outter' and Pipe- Wrench, of which the following is aspecification:

My invention consists in an improved pipecutter and pipe-wrench combinedin one implement, making a good and efficient tool for either purpose,it being very simple, and adapted to pipes of all sizes, either as awrench or a cutter, the parts which form the combination being soconstructed that either may be separated from the other, or so that thedog which completes the implement as a wrench, or the knife which makesit a'cutter, may be left 011' at the will of the manufacturer.

My object is to produce an implement that shall automatically adjustitself as a wrench to any sized pipe, and that may be adjusted to anysized pipe as acutter, both tools to be combined in one implement whendesired, so as to be cheap, simple, and efficient for either purpose.

My invention will be readily understood by reference to the accompanyingdrawings which form a part of this specification.

Figure l is a perspective view of my improved pipe-cutter with thewrench attachment thereto applied. Fig. 2 is a longitudinal sectionthereof. Fig. 3 is a view of the handle and cutter holder, with thecutter attached as when withdrawn for sharpening or adjusting. Fig. 4 isa cross section of the body of the implement, showing the openingthrough which the cutter, holder, and screw portion ofthe handle passes,and also showin g grooves or guideways made longitudinally on the innerwalls of the body of the implement.

A is the body of the implement. B is a toothed dog, which is pivoted tothe body of the implement at O, and which I term the wrench attachment.To use it as a wrench, the dog is thrown forward against the pipe, asshown by dotted lines D. A spring, E, holds it back against the body ofthe implement when not in use, and may be removed at will. On theoutside of the body, and opposite the face of the dogs B, are raisedpieces or checks N, to enable the operator to grasp short pieces of pipeor nipples between said cheek and one of the dogs. F is apiece of pipegrasped in the tool, as when about to be out.

grooves the edges of the knife or cutter G fit and slide, as also does apin or spline, B, which is a part of the holder 1. This is to guide thecutter, and to keep the cutterholder and cntterfroin turning. To makethe holder I square would answer the same purposethat of keeping it fromturning when forced forward or withdrawn by means of the screw K on thehandle P. S S are cutters provided to facilitate the operation ofcutting, especially in close and confined places, but not at all timesneeded.

These cutters are attached by means of holes in the grasping end of theimplement, and are held in place by screws or pins M. The cutters areshown in the drawing.

Having thus described my invention, what I claim as new, anddesire tosecure by Letters Patent, is l. The body A of the implement, providedwith a longitudinal hole, and with the grooves Q running longitudinallythrough the same, substantially as and for purpose set forth.

2. The dogs B hung to be thrown forward against the pipe F, and backwardagainst the body of the implement, and to be held by the spring-catch Eto adapt the tool for a wrench or cutter, substantially as set forth.

3. The holder I, carrying the double-ended or reversible cutter G, andconnected with the handle P by the swivel-joint J, and also providedwith the spline or pin R, all arranged so as to be withdrawn togetherfrom the body of the tool, substantially as and for the purpose setforth.

JOHN BREWER.
